How to get the x and y position inside an image

I have an image that I would like to be able to tap on and get the x and y position of the "tap" event.
In the tap event, e.pageX and e.pageY give me the absolute position on the screen. If the page has been scrolled, then the value is still relative to the viewport and not to the page.
How can I get the position of the tap event?
Also, how can I get the position of the image (or its container)?

I've now check every parent (container, panel and view) of the image but none them has a valid scroller...
Two of them returns an object from getScrollable(), they are both of type Ext.scroll.View.
However, they fail with this error: Uncaught TypeError: Object [object Object] has no method 'getScroller'

Checked the source, src/scroll/View.js and found something strange (I think). The getScroller() method does not seem to be implemented, there is only a comment in the file:
...
/**
* @method getScroller
* Returns the scroller instance in this view. Checkout the documentation of {@link Ext.scroll.Scroller} and
* {@link Ext.Container#getScrollable} for more information.
* @return {Ext.scroll.View} The scroller
